Yeah, it's always so cool looking. The device is using a CRT vector display, so instead of the CRT drawing each pixel row line by line, each shape on the screen is drawn one by one as small line segments. Curves are also possible, but you'd have to formulate the vector shape for it, which is harder than for straight lines.

It also looks even cooler in person, as the refresh rate is also really good due to the CRTs, if there's an old arcade close with Asteroids or similar early vector games I'd really recommend going to see it.
